Chinese Journal of Structural Chemistry 2007年第3期26卷 287-290页

作者： JIN Shou-Wen LIU Bin CHEN Wan-Zhi Department of Chemistry Zhejiang University Xixi Campus Hangzhou 310028 China

Di（2-amino-5-methyl-1,8-naphthyridin-1-ium-7-carboxylato）dichlorocuprate（Ⅱ） di- hydrate has been prepared from 5,7-dimethyl-1,8-naphthyridine-2-amine, CuCl2·2H2O and concentrated hydrochloride acid, and its structure was determined by X-ray diffraction at 298 K. The compound （C20H22Cl2CuN6O6, Mr = 576.88） crystallizes in monoclinic, space group P21/n with a = 9.102（9）, b = 12.150（12）, c = 10.619（10） A,β = 91.20°, V= 1174.1（19） A^3, Z= 2, Dc= 1.632 g/cm^3, F（000） = 590,μ = 1.208 mm^-1, R = 0.0392 and wR = 0.0984. The Cu^2＋ ion is six-coordinated by two nitrogen and two oxygen atoms from two different naphthyridine ligands at the equatorial positions together with two chloride ions located at the axial positions.
